Have you not seen how your Lord spread the shadow. If He willed, He could have made it still then We have made the sun its guide [i.e. after the sunrise, it (the shadow) squeezes and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sun light, there would have been no shadow]. 45 Then He reduces it in gradual steps. 46 It is He who has made the night as a covering for you, sleep as a rest for you, and the day for you to rise again. 47 It is He who sends the winds as heralds of His mercy and We send down pure water from the sky, 48 to revive the barren land and provide water for many creatures, cattle, and people. 49 We have explained it to them in diverse ways, so that they may take heed, but most persist in their ingratitude. 50 And if We had willed, We could have sent into every city a warner. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ And He it is Who hath given independence to the two seas (though they meet); one palatable, sweet, and the other saltish, bitter; and hath set a bar and a forbidding ban between them. 53 And it is He Who has created man from water, and has appointed for him kindred by blood, and kindred by marriage. And your Lord is Ever All-Powerful to do what He will. 54 And they serve besides Allah that which neither profits them nor causes them harm; and the unbeliever is a partisan against his Lord. 55 We have sent thee not, except good tidings to bear, and warning. 56 Say: "No reward do I ask of you for this (that which I have brought from my Lord and its preaching, etc.), save that whosoever wills, may take a Path to his Lord. 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 58 Who created the heavens and the earth and whatsoever is in-between them in six days, then He established Himself on the Throne - the Compassionate! so, concerning Him, ask any one informed. 59 When they are told to prostrate themselves before the Beneficent God, they say, "Who is the Beneficent God? Why should we prostrate ourselves before the one whom you have commanded us to?" This only increases their rebelliousness. ۩ 60
